Universal interface CG2 (4 IN conf. as DI or NTC / 4 OUT) with thermostat function

Code: EK-CG2-TP

Description

The Ekinex® EK-CG2-TP pushbutton interface is a KNX device which can be used as input and/or output module. The device is equipped with 4 configurable inputs and 4 control outputs for low consumption LEDs.

Inputs can be independently configured to connect the KNX bus to switches, pushbuttons, classic sensors (normally not communicating on the KNX bus) or any binary signals from other devices, in order to control KNX bus functions; or passive temperature sensors (NTC 10 kΩ at 25°C). The environment air mass temperature value, measured by those sensors, can be sent onto the bus or be used to control a room or zone temperature through the integrated thermostat function.

The voltage for polling the inputs is supplied within the device. The device integrates a KNX bus communication module and is realized for flush-mounting or for mounting on a standard 35 mm DIN-rail. The device is powered by the KNX bus and does not require auxiliary power supply.

Power supply

•30 Vdc power supply by KNX bus
•Current consumption from bus < 10 mA

Delivery

Delivery includes a terminal block for connection to the bus. The NTC temperature sensors for those channels configured as [AI] must be ordered separately.

Accessories

Support for mounting on a standard 35 mm DIN-rail (code EK-SMG-35) and spring for snapping on the back of Ekinex® wall-mount devices (code EK-MAR) to be ordered separately.

Integrated Thermostat Function

2-Point (ON/OFF) or Proportional (PWM / Continuous) Room Temperature Regulation

Accurate control algorithms for heating and cooling systems driving valves and fan stages.

Heating and Cooling Conduction Modes

Switching between heating and cooling operations via KNX bus or automatic changeover.

4 Operating Modes

Comfort, standby, economy, and building protection with independent temperature setpoints for heating and cooling.

Presence & Window Contact Monitoring

Automatic switching of operating mode depending on room occupancy or window opening states for maximum energy savings.

Weighted Temperature Average

Possibility to regulate room temperature by calculating a weighted average between connected NTC sensor and bus temperature value.

Functions and Application Areas

On / Off Switching & Dimming

Independent control of lighting loads with toggle, short/long press dimming or coupled channel pairs.

Shutter and Blind Drives

Full movement up/down and precise step-by-step slat positioning for motorized shading devices.

Scene Recalling and Saving

Instant recalling and memorizing of pre-configured lighting and comfort scenes.

Signal & Alarm Status Detection

Real-time state detection of signaling contacts from security equipment, technical alarms or float sensors.

Sending Values on Bus

Sending temperature, brightness, percentage or counter values over the KNX bus.

Pulse & Switching Cycle Counter

Counting input signal transitions and cycles for predictive maintenance and energy management.

4 Low-consumption LED Outputs

Driving 4 low-consumption LEDs for status feedback, orientation nightlights, or visual alerts.
